# `trim`

The `trim` filter strips whitespace (or other characters) from the beginning and end of a string:

    {{ '  I like Twig.  '|trim }}

    {# outputs 'I like Twig.' #}

    {{ '  I like Twig.'|trim('.') }}

    {# outputs '  I like Twig' #}

    {{ '  I like Twig.  '|trim(side='left') }}

    {# outputs 'I like Twig.  ' #}

    {{ '  I like Twig.  '|trim(' ', 'right') }}

    {# outputs '  I like Twig.' #}

Note

Internally, Twig uses the PHP trim, ltrim, and rtrim functions.

## Arguments

- `character_mask`: The characters to strip
- `side`: The default is to strip from the left and the right (both) sides, but left and right will strip from either the left side or right side only
